This 1.28ct lab-grown princess sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG702577493 or 702577493. Listed at 21 retailers as of October 30, 2026, with prices from HK$1,860 to HK$10,285, a HK$8,425 spread on the same certified stone. Reve Diamonds lists it at HK$10,285. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
